Molybdenum

Molybdenum is a chemical element with the symbol Mo and atomic number 42. The name is from Neo Latin molybdaenum, from Ancient Greek molybdos, meaning lead, since its ores were confused with lead ores. Molybdenum minerals have been known throughout history, but the element was discovered (in the sense of differentiating it as a new entity from the mineral salts of other metals
